Before being praised for the reboot of Castlevania, the Spanish developpers from Mercury Steam created a video game with the famous writer Clive Barker. It was called Jericho, no link with the TV show and no link with Undying either.
Clive Barker's Jericho is an horror FPS released in 2007 on xbox 360, ps3 and pc.
It was quickly sold in bargain bins because well... it's not very good. I am probably one of the few persons in the world who actually enjoyed the game, mostly for the music, the background and the retard dialogues.
